Calibrating device
First Claim
1. A calibrating device for detecting the position of an axis of a shank of a surgical instrument and of a front end of said surgical instrument relative to a first reference position determination device mounted on the instrument, comprising:
- two clamping-device carriers, each with a clamping device, defining a clamping state when the clamping devices bring the shank of the instrument into a clearly defined clamped position relative to the calibrating device;
a supporting plate (12) adapted to enable the front end of the instrument to rest on the plate when the instrument is in the clamped position; and
a second reference position determination device (42), wherein the axis of the shank is essentially perpendicular to the supporting plate (12) when the instrument is in the clamped position, the supporting plate (12) and the second reference position determination device are connected firmly to one another, and at least one clamping-device carrier can be displaced in a direction perpendicular to the supporting plate.

Abstract
A calibrating device for detecting the position, firstly, of the axis of the shank (axis of action) and, secondly, of the front end (point of action or line of action) of a surgical instrument relative to an reference position determination device 42 mounted on the rear part of the instrument, has:
two clamping-device carriers, each with a clamping device, in a clamping state the clamping devices bringing the shank of the instrument into a clearly defined clamped position;
a supporting plate 12 on which the front end of the instrument rests in the clamped state; and
a reference position determination device 42, the axis of action being essentially perpendicular to the supporting plate 12 in the clamped position, and the supporting plate and the reference position determination device 42 being connected firmly to one another.
